Struct PolicyChain 

pub struct PolicyChain {
    pub layers: Vec<Arc<dyn Policy>>,
}

Ordered policy combinator: layers are evaluated in priority order (hard-deny first). Any Deny short-circuits immediately; otherwise the first Ask is remembered while later layers keep running (a later Deny still wins — deny beats ask); if no layer denies, the first Ask wins; all Allow → Allow.

Fields

layers: Vec<Arc<dyn Policy>>
